Tailoring CsPbBr Growth Non-Polar Solvent Choice and Heating Methods.

This study describes an investigation of the role of non-polar solvents on the growth of cesium lead halide (CsPbX X = Br and I) nanoplatelets. We employed two solvents, benzyl ether (BE) and 1-octadecene (ODE), as well as two nucleation and growth mechanisms, one-pot, facilitated by microwave irradiation (MWI)-based heating, and hot-injection, using convection. Using BE and MWI, large mesoscale CsPbBr nanoplatelets were produced, whereas use of ODE produced small crystallites.
